HeiGIT produced this dataset covering 20,900 km of arterial roads in Ireland using AI analysis of PlanetScope satellite imagery from 2020 and 2024. It provides road surface predictions, width classifications, and a passability index to supplement existing OpenStreetMap data. The analysis focuses on motorway, trunk, primary, and secondary road classes.
The dataset is provided in GeoJSON and GeoPackage formats; users should consult the associated ArXiv paper (2512.04092) for specific details on the deep learning methodology.
